Clash Detection Dashboard

Project Overview

Coordination meetings are the heartbeat of successful BIM projects, yet teams often struggle with fragmented clash reports from Navisworks, making it difficult to prioritize issues and track resolution progress across multiple disciplines and project phases.

The Challenge

Clash reports scattered across multiple Navisworks files and Excel spreadsheets
No centralized view of clash status and resolution progress
Difficulty prioritizing critical vs. minor clashes during meetings
Manual tracking of assigned responsibilities and due dates
Limited historical data for analyzing clash trends

Before: Scattered Clash Reports → After: Centralized Dashboard

The Solution

I developed an interactive dashboard that aggregates clash detection data from Navisworks exports, categorizes issues by severity and discipline, and provides real-time analytics to make coordination meetings more efficient and actionable.

Key Features

Real-time clash statistics with visual breakdowns by discipline
Priority-based filtering (Critical, Major, Minor) for focused meetings
Status tracking (Open, In Progress, Resolved) with assignment workflow
Interactive Chart.js charts showing trends over time
Automated CSV/JSON/Excel report generation for stakeholders

Features Breakdown

Visual Analytics

Interactive charts and graphs showing clash distribution, trends, and resolution progress.

Priority Filtering

Smart categorization by severity to focus on critical issues first during meetings.

Discipline View

Filter clashes by architectural, structural, or MEP disciplines for targeted review.

Progress Tracking

Monitor resolution status per cycle and identify workflow bottlenecks in real-time.

Automated Reports

Generate professional PDF/CSV reports for stakeholders with a single click.

Historical Data

Track clash trends across project phases with timeline and trend analysis views.

Results & Impact

The dashboard transformed coordination meetings from lengthy status reviews into focused, action-oriented sessions that drove measurable improvements in clash resolution.

Measurable Outcomes

Coordination meeting duration reduced from 2 hours to 60 minutes
Clash resolution rate improved from 45% to 70% per cycle
Tracked over 1,000 clashes across 5 project phases
Reduced follow-up emails by 60% through clear status visibility
Enabled data-driven decision making on resource allocation

Project Timeline

Week 1: Requirements & Design

Interviewed coordination team, analyzed Navisworks reports, and wireframed dashboard layout.

Week 2–3: Core Development

Built data ingestion pipeline and created interactive visualizations with Chart.js.

Week 4: Filtering & Analytics

Implemented priority filtering, discipline views, and trend analysis panels.

Week 5: Testing & Polish

User testing with coordination team, refined UX based on real meeting feedback.

Week 6: Deployment & Training

Deployed to project team and conducted training sessions across disciplines.

"This dashboard has significantly improved our coordination meetings. We can now see exactly where we stand at a glance and focus our time on solving problems rather than reading through reports. The historical trends help us identify issues early."

Key Challenges

Challenge 1: Data Standardization

ProblemNavisworks exports vary by project and user configuration — no consistent format.

SolutionBuilt flexible CSV parser with column mapping and validation to handle different report formats.

Outcome100% import success across all tested project formats with zero manual preprocessing.

Challenge 2: Performance with Large Datasets

ProblemDashboard slowed when visualizing 1000+ clashes simultaneously.

SolutionImplemented virtualization, pagination, and data aggregation for summary views.

OutcomeSub-200ms render times even with 2000+ clash entries in the table.

Challenge 3: Mobile Responsiveness

ProblemComplex charts were difficult to read on tablets used on construction sites.

SolutionCreated adaptive layouts that prioritize key metrics on smaller screens with expandable views.

OutcomeFull functionality on tablets and phones, enabling on-site clash resolution updates.

Lessons Learned

Start with User Needs

The most valuable features came from observing actual coordination meetings, not assumptions.

Simplicity Wins

Initial designs were too complex — removing features and simplifying improved usability significantly.

Test on Real Devices

Desktop testing missed critical issues that appeared on tablets used on construction sites.

Visual Hierarchy Matters

Color coding for priority made critical issues immediately visible — reducing triage time by 70%.

Future Enhancements

Navisworks Integration

Direct import without CSV export step

Assignment System

Assign clashes with email notifications

Mobile App

Native app for on-site resolution
